This invention relates to spring tools and more particularly to a device for supporting,

the springs of a certain type of automobile to relieve strain placed thereby on the' when new shackle bolts areto be inserted or to support whenthe old shackle bolts are to be removed, f

An important and specific object of this invention is to produce a device for support ing the spring capable of relieving the tension -of the spring which is brought to bear against the shackle bolt and of such construction that it is self-locking in its spring supporting "position in. which the tension upon the shackle bolt is relieved.

A still further object of the invention is to provide a device of this character which may be very readily and cheaply produced, which will be durable and eiiicient in service anda general improvement in the art.

A further object of the invention is to provide-a device-of this character which may be readily applied to and secured in position upon either the front or rear axle of a vehicle beneath the spring thereof.

These and other objects I, attain by the construction shown in the accompanying clrawings,-wherein for the purpose of illus tration is shown apreferred embodiment of my invention andwhereinz- Figure l is'a side elevation showing a tool constructed in accordance with my invention in position ready to engagewith a spring of the vehicle; I. 4 d p 7 Figure Qshows the tool engaged and in the spring supporting position, parts being broken away to ,illustrate the. construction; Figure 3 isasection on the line 3 3.of Figure 2; p

drawings, the numeral 10 generally designates a base plate having at its ends down turned flanges 11 and 12 for engagement withthe axle 13 of a vehicle. The flange 12 is provided with an arcuatenotch 14, sothat it may accommodate the cylindrical housings 13 of the rear axles of-the vehicle and have its outer face abutting "against the differential housing 15 of this rear axle.

Adjacent its opposite. end, the base plate has extending upwardly therefrom at oppo site sides thereof standards 16, which standards are provided in their upper faces with notches 17 closed by-pins 18ito provide pivot openings 19 receiving pivot lugs 20 formed on the inner surfaceof spaced Qarms21 of a link22. The arms of'the linkare rigidly connected by a shaft 23 andthe outer sur-;

face of each arm is formed with a socket 24L to receive the end of an. operating bar,25.

The end of the bar engaging in these sock-- ets is slightly bent'to oneside, as at26,so

that the handle end of the bar, is well spaced from the axle when the: bar is in position.

Each standard has further vformed therein an opening 27, one of these'openings receiving an'arm 28, the. free end of which has a chain- 29 or equivalent fiexible'ele'ment attached thereto and adapted for :passage about the" axle: ofa yehi'cletosecure the same againstniovement where the inner end of the base plate cannot "conveniently be arranged against some]. obstruction. spring engaging plate 30 isprovided, this plate being formed at its side face'with up standing lugs orfianges 31' adaptedtolen gage opposite side faces of a spring 32t0 prevent transverse displacement of the plate 30 with relation to the spring. This plate is further formed with. transversely extending grooves 32 for the reception of connection bolts 33 offspring .clips 34' and 'the'sides of the plate in alignment with thegrooves are notched, as at 35, for the reception of :-the

clips themselves. The under-surface of this plate has atits side edgesdepending pairs of lugs SG adapted-tO receive therebetween the; shaft 23 of the link 22,: the ends of the lug being about the to prevent p sep'aration ofthe link and spring engaging plate. f H a he' se-ettbeid qe,the e 19 is placedin position upon the aiile with its flanges ll'and 12 in engagenient with the It the serieseb he t ee? eleis and the clip' bol'ts of the 1: spring; engage in "the grooves' 82 thereof; Gq t n etl in ti n ofthe h ndle bar we rause the spring tofbe elevated and the. ten} sion placed thereby ape; the spring shackle S relieved]sothattheholts otthe shackle t shekl e l' l sar e e tad tr e n nings which they are rovided, he
